Hemp Insulation Batts and Fibre Composites

Beyond walls cast on site, hemp fibre is manufactured into flexible batts and semi-rigid boards for roofs, floors and stud cavities, and pressed with resins into panels and moulded parts for furniture and vehicle interiors. This cluster looks at how hemp insulation handles vapour, sound and summer heat, what binders and fire treatments are typically used, and how natural-fibre composites compare with glass fibre on weight, stiffness and end-of-life disposal. Aimed at builders, specifiers and product designers.
